我在sql查询中添加了一个复选框过滤器来过滤一组视频。我曾经尝试过分页，我必须对像SELECT * FROM movies之类的简单直接sql查询的结果进行分页，但是我有一段时间试图让它与过滤后的查询一起工作。我的分页功能
分页功能

$nextlabel = "Next ›";
$lastlabel = "Last ››";
$page = ($page == 0 ? 1 : $page);
$start = ($page - 1) * $per_page;
$prev = $page - 1;
$next = $page + 1;
$lastpage = round($total/$per_page);
$lpm1 = $lastpage - 1; // //last page minus 1
$pagination = "";
if($lastpage > 1){
$pagination .= "<ul class='pagination'>";
if ($page > 1) $pagination.= "<li><a href='{$url}page={$prev}'>

问题是我尝试了不同的方法，但我不能让分页功能与过滤器SQL查询一起正常工作。我如何在latest.php中实现分页，任何有效的分页功能都会非常有用。
